MOLDED AUTOMOTIVE VISOR
An automotive visor includes a core member and an integrally molded cover layer. The core member may be formed as a single component, or may comprise two sections that are joined together in confronting relationship. The cover layer can be molded to completely encapsulate the core member, or it may be applied to selected areas of the core member. The cover layer is formed from a material having a hardness that is relatively lower than that of the core member, to provide an aesthetically pleasing feel to the finished visor.
The present invention relates generally to visors for automobiles, and more particularly to an integrally molded visor.
BACKGROUND OF THE INVENTIONVisors have been provided in automobiles to shield occupants' from glaring sunlight which enters the vehicle interior through the windshield or through the side windows. Conventional automotive visors are moveable from a stowed position adjacent the roof or headliner of the automobile, to a downwardly extending position adjacent the windshield to help block the sunlight, as may be desired. Conventional visors are also pivotable from the position adjacent the windshield to a position adjacent a side window, as known in the art.
Conventional methods of manufacturing automotive visors involve forming a core member, generally from plastic or cardboard, and subsequently stretching and wrapping a cover material, such as fabric or leather, over the core member. After the cover material is applied to the core member, it is staked, glued, or otherwise secured to the core member. These conventional methods require multiple components and manufacturing steps which increase the overall cost of producing the visors. In addition, these conventional methods are prone to cause variation in the quality of the finished product. A need therefore exists for an improved automotive visor that overcomes these and other drawbacks of the prior art.
SUMMARY OF THE INVENTIONThe present invention provides an automotive visor and method of manufacture that greatly reduces the time and effort to produce the visor, while at the same time facilitating uniform quality of the produced visors. In one embodiment, the automotive visor includes a core member having an outer surface. A cover layer is integrally molded over the outer surface of the core member, and may either completely encapsulate the core member, or may be applied only to selected areas of the outer surface. In one embodiment, the core member is formed from polymeric material and the cover layer has a hardness that is relatively lower than that of the core member to provide a soft feel that is aesthetically pleasing. In another embodiment, the cover layer may be textured to simulate fabric or leather cover material.
The core member may be formed by various molding methods and may comprise a single unitary piece, or multiple sections that are joined together to form the structural core of the visor. In one particular embodiment, the core member includes first and second sections that are hingedly coupled together and folded toward one another in a confronting arrangement.
In another embodiment, a method of forming an automotive visor includes forming a visor core from polymeric material having a first hardness, integrally molding a cover layer on the outer surface of the core, with the cover layer formed from polymeric material having a hardness relatively lower than the first hardness, and coupling a support arm to the visor core for mounting the visor to an automobile.
The features and objectives of the present invention will become more readily apparent from the following Detailed Description taken in conjunction with the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGSThe accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and, together with a general description of the invention given above, and the detailed description given below, serve to explain the invention.

Referring now to
A cover layer 26 is integrally molded onto the outer surface of the core member 24. When the core member 24 is formed from polymeric material, the material for the cover layer 26 may be selected such that it has a hardness that is relatively lower than the hardness of the core member 24. The lower hardness of the cover layer 26 provides a soft feel to the visor which may be desired to improve the aesthetics of the visor 12. The molded core member 24 may be formed from thermoplastic olefin, (TPO) acrylonitrile butadiene styrene (ABS), styrene maleic anhydride (SMA), polycarbonate/acrylonitrile butadiene styrene alloy (PCABS) or other materials suitable for molding the structural core member 24. The cover layer 26 may comprise vinyl, thermoplastic elastomer (TPE) or other materials for molding the cover layer 26 integrally with the core member 24.
Advantageously, the visor 12 may be formed in a two-shot molding process wherein the core member 24 is formed during a first shot of the molding process, and the cover layer 26 is integrally formed over the core member 24 during the second shot of the molding process. After the cover layer 26 has been molded onto the core member 24, the mounting arm 20 and pin 22 may be coupled to the core member 24 to complete the visor 12. Alternatively, one or more of the mounting arm 20 and pin 22 may be integrally molded with the core member 24.
While
The core member 24 may be molded according to various methods known in the art. For example, the core member 24 may be formed by injection or compression molding to create a single unitary piece, as depicted in
While the present invention has been illustrated by the description of one or more embodiments thereof, and while the embodiments have been described in considerable detail, they are not intended to restrict or in any way limit the scope of the appended claims to such detail. Additional advantages and modifications will readily appear to those skilled in the art. The invention in its broader aspects is therefore not limited to the specific details, representative apparatus and methods and illustrative examples shown and described. As one example, although polymeric materials are disclosed for use in forming the inventive visor, it will be appreciated that other materials may be used instead or in addition to polymeric materials. Other departures may be made from such details without departing from the scope or spirit of Applicants' general inventive concept.
